Absolutely! There are many times in games that we have virtually simultaneous whistles, sometimes a violation and foul or other times two fouls on different players. It's up to the partners to communicate well with each other, decide which happened first (thus nullifying the "second" foul or violation), and proceed accordingly.

Last night in an 8th grade boys blowout. A1 is dribbling up the side and is pushed from the side by B1. I called the foul, but after the first foul and right at my whistle, A2 set an illegal screen on B1. The coach objected, naturally, and I told him that the ball was dead on the first foul. Therefore, there couldn't be another common foul on that play. Was I rignt, or is the ball live until the whistle? There was no shot involved.

You are correct. Unless the "second" foul was intentional or flagrant you ignore it. It happened during a dead ball. You had already seen the "first" foul and blown your whistle.

Furthermore, a whistle does not always cause the ball to become dead--i.e. the violation before the whistle caused the ball to be dead.
